PEEK yarn is a thermoplastic aromatic multi-filament yarn obtained by melt-spinning polyetheretherketone resin at high temperatures.
PEEK yarn is a thermoplastic aromatic multi-filament yarn obtained by melt-spinning polyetheretherketone resin at high temperatures. This kind of yarn has excellent properties such as high and low temperature resistance, chemical resistance, flame retardant, low friction coefficient etc.
Excellent temperature resistance.
Naturally anti-flammable.
Superb corrosion resistance.
Extremely high-temperature hydrolysis resistance.
Good tensile strength.
Great abrasion resistance.
